The mechanical properties of hot rolled picked deep drawing plate were investigated with thickness of SS400C3 plate changing under new technological parameters of CSP. Results showed that the mechanical properties of SS400C3 plate depend on thickness. The δ_s and δ_b were reduced and the δ increases with an increase in the thickness of the SS400C3 plate. The technological parameters were adjusted by the thickness of SS400C3 plate.

Keywords: CSP; Continuous metal cast process; Rolling technology; Mechanical property.

1.Introduction

Compared with the corresponding grade cold rolling plate, the hot rolling and pickling deep drawing board can omit the cold rolling and annealing process, reduce the production cost, and the hot rolling pickling deep drawing board has the high strength, high elongation [1, 2] and good formability. According to the inherent characteristics of CSP process, the process conditions of SS400C3 production of [4], low carbon, low silicon, low manganese, appropriate relaxation of C, [5-10] and Si were used in the design of chemical composition.

2.Experimental Materials and Methods

Adopt front cooling: value: 1 First. Cooling water setting 75%. T 6.0mm, head of 6 meters is not cooling, T > 6.0mm, the head of 8 meters without cooling. The average mill inlet temperature at 1041 degrees Celsius, finishing temperature at 854 degrees Celsius, coiling temperature at 601 degrees Celsius. From the temperature of the average temperature control of the key point to achieve the standard temperature control requirements, the intermediate billet set up to meet the requirements of the regulations.

The rolling speed is changed with the different thickness steel witch will be rolled form thickness of 50 mm to 1~4 mm thick steel, and the process parameters such as Table 1.

The chemical composition of the experimental steel was SS400C3, and the Si, P and S of the experimental steel was lower than that of the experimental steel, as shown in Table 2. Analysis of the chemical constituents in the steel plate by using the PROFILERHR glow spectrum analyzer.

The steel strip samples are drawn from the outer and inner ends of each roll, vertical to rolling direction, GB/T228-2002 and 1/4 of the strip width −35 and 1/2. The sample is made into tensile specimens. The mechanical properties of the specimens are tested by using 20mm * 80 GB/T228-87 standard test.

3.Experimental Results and Discussion

3.1.Mechanical performance analysis

Table 2 for the detection of SS400C3 steel plate thickness specifications and mechanical properties, through the thickness of the 1.8~4mm and the width of the 1210~1600mm number of SS400C3 rolling plate for statistical analysis, experimental results are more universal.

Table 1.The technological parameters of CSP.

Table 2.Mechanical properties of SS400C3 plate.

From the physical performance test results, the performance stability is better, the strength of the surplus amount is appropriate, the extension rate fluctuations slightly larger. 3.0mm's SAPH400 thickness specifications of the low tensile strength, yield strength of the surplus, the extension rate also meet the standard requirements. To adjust the process of SAPH400, the first three sections of the cooling pipe before the restoration of cooling mode to the front cooling, Vlave Frist from 13 to 1, the cooling method to adjust for the strong cold, in addition to consider increasing the C content, to improve the tensile strength.

3.2.Organization analysis

The microstructure of SS400C3 steel was shown in Table 3, microstructure and morphology of F+P. The microstructure of SS400C3 steel was composed of ferrite and pearlite, and the grain size of the kinds of steel was more uniform, and the grain size of the three steel was uniform. The grain size of the 1/4 is slightly higher than that of the center. This is also the main reason for the difference of mechanical properties between different rolling plate thicknesses.

Table 3.Microstructure and grain size analysis of SS400C3 plate.

4.Conclusions

Through the analysis on the mechanical properties of CSP rolling plate S400C3 seen SAPH400 3.0mm specifications tensile strength is low, standard is equal to or more than 400MPa actual 408Mpa. Close to the lower limit, the production layer of cold front set tube has been restored for use. The first valve 1 fore stage cooling, adjust the cooling mode by a weak cold adjustment for strong cold, the tensile strength increased. In addition, the content of C can be improved, the content of Mn can be decreased, and the ratio of yield and yield can be decreased.
